Inkjet droplets of radioactive material enable quick, precise testing at NIST
Researchers at the National Institute of Standards and Technology have developed a technique called cryogenic decay energy spectrometry capable of detecting single radioactive decay events from tiny material samples and simultaneously identifying the atoms involved. In time, the technology could replace characterization tasks that have taken months and could support rapid, accurate radiopharmaceutical development and used nuclear fuel recycling, according to an article published on July 8 by NIST.

This paper presents a conceptual design of a laser fusion reactor for direct irradiation implosion of a DT fuel pellet. The reactor is driven by a laser diode (LD)-pumped solid state laser. 4 MJ driver energy yields the maximum gain of 150. The driver will be operated at a repetition rate of 12 Hz. We propose the four module chamber-one laser system. Each module chamber is operated at 3Hz. A first wall is made of liquid-lithium-lead flows. The flows are guided by woven ceramic pipes, protecting the structural wall as well as breeding tritium. By adopting currently existing technologies, we designed a concept of a high efficiency- and high repetition rate- LD-pumped solid state laser driver.
